' Application filed October 5,1903. Serial No. 175,729. (No model.)

To all whom it m/alyconce rm Be it known that we, RoswELL A'. LANoEY and CHARLES W. SMITH, of Townsend, county of Middlesex, and State of Massachusetts, 5 have invented certain new and useful Improvements in Mechanism for Finishing the Ends of Barrels, of which the following is a specificasliding rod C. The objects of our invention are as follows:

tion.

I to provide means for smoothing or'finishing the ends of abarrel that will accomplish the 2 plishing the same, Figure 1 represents a front elevation of a rotary cutter-head with the cutters mounted thereon. Fig. 2 represents aseotional view through line 2'2, Fig. 1. Fig. 3 is a sectional View through line 3 3, Fig. 1.

'5' Fig. i is a view of the chamfering-cutterand the block to which it is attached. Fig. 5 is a sectional view of the leveling-cutter and the block to which itis attached. Fig. 6'isa view of the howeling-cutter and the supporting- 3 block for same. Fig. 7 is a sectional view of the crozing-cutter and the'supporting-blOck for same. Fig. 8 is an enlarged view'of the howeling cutter, which better illustrates its shape and the method of holding it. Fig. 9 is an enlarged view of the crojZing-cuttenshowing its shape and the shape of the cutting edge. Fig. 10 is an end view of the croZing-cutter, which better illustrates its shape. Fig. 11 is a sectional view through 'line 11 11, Fig. 1,

4 showing a section of therevolving cutter-head and the method of securing the 'two support-- ing-blocks and slide supporting same.

In the drawings, A illustrates a revolving head. B is a dovetail groove running across the face of the revolving cutter-head, and B is a similar dovetail groove running across the face of the revolving cutter-head A at substantially right angles to the dovetail groove B.

C is a slide-block dovetailed to fit and slide in the groove B and is of a length sufficient j to extend very nearly the whole length of said groove and has on its inner face an inwardly,- extending cam portion C, having thediagonal slots C cut in its inner faces arranged to receive the pins C attached to the end of the The object of the cam C pin C and the sliding rod C is as follows: When said sliding rod C is moved longitudinally or endwise at right angles to the face of the revolving cutter-head A, it will move the slide-block C endwise and cause the cutters mounted thereon to contact with the end of a barrel. I

' Mounted upon the slide-blockO are cuttersupporting blocks D and D, secured thereto by the T-head bolts D D The bolts-D D? have T-shaped heads adapted to fit and slide in the T-shaped slot D in order that said. blocks D and D may be adjusted longitudinally in or out from the center of the revolving cutter-head A. Adjusting-blocks E and E are also attached to the. slide C by similar bolts and have threaded therein adjustingscrews E E The purposeof these adjustingscrews is as follows: When it is desired to sharpen the cutters mounted in the cutter- 'blocks D and D, the bolts D"D are loosened and thecutters and cutter-supporting blocks removed, the cutters being sharpened while attached to the blocks; When sharpened, they may be returned to the exact position they occupied before removaLas shown in Fig. 1, or again in contact with the-screws E E thereby preserving the same position that they occupied before being removed. The. screws E E 'also serve the purpose of allowing the operator to get a fine adjustmentof the cutters supported by the cutter-blocks D and D.

Fis the leveling-cutter and is adapted .to be moved inward from the outside of the barrel, thereby .cuttinginward, making the outside edge of the end of the barrel after being cut or leveled by said cutter F smooth.

G is the chamfering-cutter, which moves outward to chamfer the inside edge of the barrel. The movements of the cutters and G are more clearly shown in Figs. 4 and 5.

Short sliding blocks H and I are mounted in and slide in the dovetail groove D. The inner ends of these sliding blocks are provided with the inclined slots K and L, in which the pins M and M are free to slide. These pins M and M are mounted upon a cross-piece M which in turn is attached to the slide C and is moved thereby. It will be seen that any movement of the slide C in the direction of the arrow will cause the block H to move outward and the slide-block I to move outward and be drawn inward again. The purpose of the double movement of the slide I will be more fully explained hereinafter.

H is a tool-supporting block adjustably attached to the slide-block H, and H is an adjusting-block secured to the slide H, having an adjusting-screw H threaded therein in such manner as to contact with the inner end of the block H. The slide I has also adjustably mounted thereon the tool-holding block I and adjustingblock I", having threaded therein the ad justing-screw I There is mounted upon the tool-block H. the howeling-cutter F, and upon'the tool-block 1' is mounted the crozing-cutter G. The purpose of the adjusting-block I and the adjusting-screw I is the same as has been stated for the ad justingblock E and the adjusting-screw E 1 The operation of our improved barrel-finish ing revolving head and the cutters mounted thereon is as follows: Referring to Fig. 3, when the slide-rod C is moved inward in the direction of the arrow the pin Q will slide downwardly in the slot C thereby moving the slide C in the direction of the arrow, causing the leveling-cutter F to move in ward and cut off the end of the barrel and the chamfering-cutter G to move outward toward the inside of the barrel and chamfer the chime thereof, as shown in Fig. 4:; but the cutter F is so positioned as to contact with the outside edge of the barrel and commences to cut it before the cha'mfering-cutter G commences its cut, so that said leveling-cutter F will have completed its out and have moved beyond the end of the barrel, as shown in Fig. 5, before the chamfering-cutter G has completed its cut, as is shown in Fig. 4. This arrangement and rotation of the operation of cutters F and G produces a smooth end and leaves the inner and outer edges of the end of the chime smooth and free from any indentations or slivers, which is a very essential point in the construction, especially of pine barrels. The cutters F and G are arranged to move outward to cut a howeling-groove and a crozing-groove to receive a barrel-head. The

shape of the crozing-eutter G is more particularly shown in Figs. 9 and 10, which shape enables the operator to cut a very smooth crozing; but the cutter G is so shaped that it must perform its out quickly or substantially in two revolutions of the revolving cutter-head; otherwise it would rub against the wood, heat, and draw its temper. For this reason the block I is provided with what might'be termed the double cam-surface L, in order that the crozing-cutter G will quickly perform its out and be withdrawn from the material while the howeling-cutter F is completing the operation of cutting the howelgroove- The shape and the rotation in which the cutters illustrated in the drawings perform their operation of finishing the ends of a barrel is the important and essential feature of this invention, for in machines heretofore designed for finishing the ends of barrels wherein the cutters are held rigidly in a revolving cutter-head and moved thereby to contact with the barrel it has been impossible to finish the ends of barrels smoothly, for the reason that the cutters would beat and get dull and tear or remove the material by abrasion. These objections have been fully overcome by the form of cutters and the manner in which they perform the operation of cutting in our device.

This application is designed to supplement our application for a patent filed April 1, 1903, Serial No. 150,592.

Havingdescribed our invention and its mode of operation, what we claim is 1. In a revolving cutter-head for finishing the ends of a barrel, a cutter-supporting head; radial grooves in said cutter-supporting head; a cutter-supporting device slidably mounted in said" grooves; a slide-rod mounted to move at right angles to the face of said cutter-supporting head; pins in the inner end of said slide-rod; inclined cam-slots in said cuttersupporting slide; a cross-bar attached to said cutter-supporting slide having pins in its outer ends; a pair of cutter-supporting slides mounted in two of said grooves; cam-slots in their inner ends adapted to receive the pin in the cross-bar; a erozing and a howeling cutter mounted on said slide-blocks and adapted to be moved radially through the movement of said cross-bar as set forth.

2. In a revolving cutter-head for finishing the ends of barrels, radial grooves in the face thereof; a cutter supporting slide slidably mounted therein and extending substantially across the face of said cutter-supporting head; independent cutter-supporting slides in the other grooves in said cutter-supporting head; means for moving the first-named slide; and means for moving the last two named slides from the first slide as set forth.

3. In a revolving cutter-carrying head for finishing the ends of barrels, radial grooves in the face thereof; a cutter-supporting slide slidably mounted therein and extending substantially across the face of said cutter-supporting head; independent cutter-supporting slides in theother of said grooves; cams for moving said first-named slide; a ehamfering the independent slides from the first slide as set forth. I

4. In a revolving cutter-carrying head for fixing the ends of barrels, radial grooves in the face thereof; a cutter-supporting slide slidably mounted therein and extending substantially across the face of said cutter-supporting head; independent cutter-supporting slides in the other of said grooves; cams for moving said first-named slide; a chamfering and leveling cutter adjustably mounted thereon in such manner that the leveling-cutter Will cut from the outside and the chamferingcutter from the inside of the ends of a barrel,

and complete its out after the leveling-cutter has completed its cut; and means for moving the last two named slides from the first slide in sequence so that the crozing-cutter will complete its out before the hoWeling-cutter has completed its out.

In Witness whereof We have hereunto set our hands, in the presence of two subscribing Wit nesses, this the 30th day of J uly, A. D. 1903.
